haggling is back. and it feels so good.

There is no feeling more satisfying than snagging a great deal on something expensive. It's probably a better high than most drugs. A couple smarty-pants MIT grads created a new app called Theorem, in which you can essentially "name your own price" for clothing and accessories from up-and-coming high end designers. Although popular sites such as Gilt and RueLaLa offer memberships to access deeply discounted luxury goods, this is the only app that lets the consumer call the shots. And the best part? You'll end up with some new threads at at least 50% off!
